A lot of gas tanks (at least the one's I've seen) aren't totally smooth across the bottom. There's the little dimple well where the pickup sits at the lowest point, but there are other low spots where water can pool up and hide, make the air in the tank humid, and cause frost in the tank when it gets cold. Hopefully you have this cheap and easy issue (hopefully me too).
Another possibility. I've noticed electric motors act funny when they start going bad. They'll work for a while, then they won't, then they will, so on, so forth, then they eventually die completely. Megan's old Grand Am had a fuel pump starting to go bad before she traded it in and it was acting up intermittently just like you're talking about. I don't know the technical name, but the guy at the craft shop hooked up a super duper tester tool thingy to it while it was running, showed me a screen that looked like a heartbeat on an EKG, and we saw the pump wasn't working exactly right.
